DESCRIPTION

This module implementations the W3C's DOMException and EventException interfaces. HTML::DOM::Exception objects stringify to the message passed to the constructer and numify to the error number (see below, under 'EXPORTS').

METHODS

$errr = new HTML::DOM::Exception $type, $message

This class method creates a new exception object. $type is expected to be an integer (you can use the constants listed under 'EXPORTS'). $message is the error message.

$errr->code

Returns the error code. Same as 0+$errr.

If data is specified for a node which does not support data

NO_MODIFICATION_ALLOWED_ERR (7)
